ISA 110×110×12 Weight, Dimensions and IS 808 Properties
ISA 110×110×12 weighs 19.5 kg per metre as per IS 808:1989.
- One 6-metre length weighs 117.0 kg · one 12-metre length weighs 234.0 kg
- Leg 110 mm × thickness 12 mm · root radius 12.0 mm
- Cross-sectional area 24.88 cm² · Iuu = 253.0 cm⁴
ISA 110×110×12 is the heavier 110 mm equal-leg angle in IS 808:1989. At 19.5 kg/m it is used for heavily loaded back-to-back compound chord members in large-span trusses and primary built-up column sections where the 10 mm variant is under-capacity.

Dimensions and properties as per IS 808:1989 (Reaffirmed 2001). Mass tolerance: ±3% per piece as per IS 808. u–u is the major principal axis at 45° to both legs; v–v is the minor principal axis. Zvv is not published in IS 808:1989 for angle sections.
Common Applications of ISA 110×110×12
ISA 110×110×12 is used for heavily loaded compound chord members in large industrial trusses, primary built-up column sections under very high axial load, heavy wind bracing members, and large gusset plate bolted connections. Available from JSPL, Tata Steel, and SAIL.
Worked Example
A structural fabricator in Surat needs ISA 110×110×12 for 8 heavily loaded bottom chord members, each 6 m long, for a 28 m span truss. Total length = 8 × 6 = 48 m. Weight = 48 × 19.5 = 936 kg (0.936 tonnes). At ₹62,000 per tonne (Surat, May 2026), material cost is approximately ₹58,032.
